Face mask visualization for a robotic head
Pospíchal, Tomáš ; Brablc, Martin (referee) ; Appel, Martin (advisor)
This bachelor thesis deals with face exposure visualisation using backward projection. Image calibration is implemented for correction of distorsion and brightness change caused by curved projection plane. Identification of deformation is done by projected checkerboard patern . For deformation method of Moving Least Squares (MLS) is used. Test tool is designed and projector upgrade for shorther throw distance is implemented.

IR camera data processing
Malík, Dalibor ; Petyovský, Petr (referee) ; Richter, Miloslav (advisor)
The aim of this master’s thesis is to give information about the thermo camera measurement with error minimization. The basic concepts of thermography are explained with an implementation of postprocesing technique which uses graphically modified thermogram back projected to the scene. This is closely related to the scene design, calibration of thermal camera with projector, image rectification, thermogram processing with highlighting of interesting information and implementation of control elements as the user interface. The results obtained are analyzed and re-evaluated.

Design Proposal for the Switching Mechanism of a Tourist Car Headlamp
Škývara, Tomáš ; Porteš, Petr (referee) ; Ramík, Pavel (advisor)
The purpose of this thesis was to create proposal of mechanism for the tourist shutter, which could replace the original solution for projector currently used by Visteon-Autopal. The thesis was focused on background research of known solutions and proposal of new mechanism. The proposal was processed from mechanical site at first. All proposals were created to get inspiration before final design of tourist shutter for projector.

Structured-light 3D scanner
Hadzima, Jaroslav ; Chromý, Adam (referee) ; Jelínek, Aleš (advisor)
3D scanner is a device capable of creating a model using analysis, most commonly from image data. 3D scanners could be divided into two major groups, contact and noncontact scanners. Aim of this study is to interpret problematics of 3D scanning with structured light. Specifically usage of Gray code patterns. There is step by step evaluation of individual hardware and software obstacles and possible errors, from calibration to final point cloud. In next section, there are included tests determining quality, precision and accuracy of scanning with given method. System is applicable to mobile robots and yet fully remotely controlled. The majority of enumerations is taking place in Raspberry Pi 3 model B, just visualization alone is done from computer.

Realization of a structured light 3D scanner
Přikryl, Matouš ; Brablc, Martin (referee) ; Adámek, Roman (advisor)
The beginning of the thesis presents 3D scanner types. Following part describes how the structured light 3D scanners works. It takes into the account whole scanning process and adress problems like calibration, optical triangulation, or surface reconstruction of 3D objects. The second half of the thesis is focused on the implementation of simple 3D scanner, using Machatronics laboratory hardware. It also describes scanners behaviour in different conditions.

High resolution digital light source design for automotive industry
Machač, Petr ; Rubeš, Ondřej (referee) ; Věchet, Stanislav (advisor)
Digital high definition light sources are a new way of communication between car and other road users. By intelligent switching of high beam or projection of various warning or information symbols on the road a lot of even tragic traffic accidents can be prevented. The purpose of this thesis is to explore contemporary automotive lighting technologies, then to choose the appropriate technology for high definition light source and design a prototype of mechatronic lighting systém.

Board Games on Interactive Table
Svoboda, Petr ; Najman, Pavel (referee) ; Beran, Vítězslav (advisor)
This thesis focuses on the application of the tangible user interface and spatial augmented reality principals for playing board games. For this purpose, a system called interactive table was developed. It is both hardware and software solution. The hardware part solves the installation of a depth camera and a projector located above the table. The software solution deals with calibration of the depth camera and projector system using known procedures for camera calibration on the one hand, on the other hand it solves tasks from the field of computer vision. This perceptional part is the core of the whole thesis and for the purposes of playing board games it provides information about the location of the physical game object, physical game board and the calculations of mask for masking distracting objects. An educational application was developed for the purposes of demonstration of the system options. The interactive table offers new possibilities for playing board games in a real-world environment by the combination of the augmented reality elements with real-world objects and the related new user experience.

Projected User Interface - Board Game
Vizina, Petr ; Najman, Pavel (referee) ; Zahrádka, Jiří (advisor)
This paper deals with study of possibilities and use of projected user interfaces, which are based on a camera-projector system. The purpose is to create functional application, that using projector to display user interface of application and camera for capturing user interaction with the projected interface. Created application is supposed to be a simulation of board game called "Mill". The result is a functional application of board game, that utilizes tools for calibration of the camera-projector system with physical calibration pattern and hand detection in captured scene.

3D dental scanner
Kotek, Lukáš ; Sekora, Jiří (referee) ; Balogh, Jaroslav (advisor)
The general aim of my master´s thesis is to study the actual principles of 3D scanning, the anatomy of human teeth, use of 3D scanning in dentistry and other medical fields. Another part of this thesis is about software and hardware design of 3D scanning system, which enable us to scan dental casts. This design is using webcam, projector and turntable. The principle of scanning is based on the activ triangulation. The output of 3D scanner is a horde of spots, which are used for reconstruction of a surface. The reconstructed surface is finally saved as .stl format.
